RUDOLPH CONRADER, OFFRIR, PENNSYLVANIA.

GOVERNOR.

Specification of Letters Patent.

Application filed March 14, 1904. Serial No. 198,082

To @ZZ whom it may concern: p

Beit known that I, RUDOLPH CONRADER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improve'- ments in Governors, of which the following is a specification.

This invention relates to governors and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims,

'The invention is illustrated in the accompanying drawings as follows: A

Figure 1 shows a central section of the governor, Fig. 2, a side elevation of the same', Fig. 3, a section on the line 3 3 in Fig. 2.

*A marks the valve-chamber a, the valvediaphragm therein 5 B, the ordinary governorvalve b, the valve-stem extending therefrom. Secured to the valve-chamber is the valve-frame A. The valve-stem extends up into this frame and is secured-to the yok'e B. The upper end of this yoke is provided with a step-bearing t', on Which the pin C rests. The pin extends out through the governorcarrier M to a head-block c. The head-block c has the pins c, on which are pivoted links D. These links are pivoted, by means of the pins e, with the weights E, the weights forming the centrifugal element of the governor. The weights are driven with the carrier M by means of the gear m. This gear m is driven by the beveled gear n. The gear n is xed on the shaft N. The drive-pulley O is arranged on the shaft N. The centripetal element of the governor is connected with it through the lever F, Which engages the yoke B. The lever F is arranged on the rod j' and has the extensions F extending out Without the governor-frame A. Resting on the outer end of the extension F is the spring G, which forms the centripetal element of the governor. The

. yoke H is arranged on this spring G and is extended by the'pin h, which rests on the piston I in a pressure-cylinder I. The springs H are arranged at each side of the yoke H and normally hold the yoke in its normal position. The pressure-cylinder I is connected With any fluid-pressure receiver connected with a pump controlled by the governor. It enters the cylinder 7c through an opening K, passes, by the passage t, into the pressure cylinder or chamber I. The passage i is i controlled by a needle-valve J. A vent i is provided for the chamber I. By proportioning the passage t and vent t the variation of the pressure in the receiver may be inlratentecl May 22, .1906.,

tensiiied. A piston K controls the valve J. A

It has the stem k extending against the rocklever L. The movement of the piston K is opposed by the spring l. This peculiar pressure device, in connection with the governor,l

does not form the special subject-matter of this application. Any pressure device may be used, if desired.

None of the structure so far as hereinbefore described forms lany of the specific subject-matter vfor this application. The general features of the centrifugal governor are shown in my patent of November 14, 1899, No. 636,764, and some of the features of the lressure device are shown in my patent of ecember 25, 1900,- No. 664,468.

In all governors, and particularly in the governor herein shown, diliculty has been experienced in oiling the carrier-bearing, the carrier M being journaled in the frame A, and With the usual operation of the governor it is rotated rapidly. I have overcome this difficulty by providing the stem C with a passage cz. The passage c2 extends into a cavity m, formed between the carrier M and the pin c2, this cavity forming a reservofr for a lubricant, as oil. A passage m2 extends from this cavity to the carrier-bearing. An opening e is arranged in the governor-Weights immediately at the axis of the pin, so that oil may be introduced to the passage c2 when the governor is stationary or in motion. The bearing between the pin and the carrier is also lubricated in this manner, as is also the step b. I have also provided means for ofling the pivots of the Inks D. These links being adjacent to the cavity cfl have the openings d, wli' ch are arranged to receive the overflow from the cavity c2. Passages d extend through the links to the j oint formed on the pivot e. In this way the parts of the governor are completely lubricated,land the oil may be introduced whfle the governor is stationary or in motion. l

In my patent of November 26, 1901, No. 687 ,450, I have shown and claimed automatic stop device for a pump-governor. In the present application I provide an improved forni of automatic stop for pump-governor. The rod f of the lever F extends outwardly parallel with the shaft N. At its outer end there is arranged a finger Q, which is locked with the rod f by the pin q. The linger Q is in the path of a cam P. The cam P is journaled on the end a of the part a2, and the IOO IIO

journal ofthe cam is consequently practically concentric With the shaft-.NA An arn'i P e'x'-` tends from the cam P and has the pulley PZ arranged to ride on the belt (shown by the dotted lines) when the governor s operating normally. When the belt is disarranged, broken or otherwise, the pulley P2 forms4 a Weight which drops, carrying 'with it the earn Pf This @neming 11p/Q11. @heile @HQ `reeks the. rod f andfdepressefsfthe lever ft'flius shutting Off thaggidvemrg.:
